Kelly is one of the most popular people in the city, but residents have a message for him: “don’t give up your day job,” reported political reporter Marcia Kramer.

Asked in an exclusive CBS 2/Rasmussen poll if Kelly should run for mayor, 33 percent said “yes,” while 49 percent said “no.” Another 17 percent said they were not sure.

People like the police commissioner — he has a 67-percent approval rating — but asked if they would vote for him for mayor, 42 percent said they were either very or somewhat likely to cast a ballot for him, while 47 percent said they were not very or not at all likely to vote for him.

Political consultant Hank Sheinkopf said he thinks the findings show people want Kelly to stay in the NYPD, not leave to seek elective office because he’s kept the city safe from terrorism in this post-9/11 world.

“But they also don’t want the police commissioner running for mayor as police commissioner. The separation between policing and politics in this town is something that goes very deep into people’s psyche,” Sheinkopf said.

“I don’t really like the idea of a police commissioner being in politics. I think they should be separate. It doesn’t look good,” Bronx resident William Johnson said.

When asked if she would vote for him, Greenwich Village resident Eileen Hochman said, “I don’t know, I don’t know. Up ‘til now I might … I might vote for him.”

“I think he’s been a decent police commissioner, but mayor is a whole different job,” added Pat Gibson of Midtown.
